Raymond Mill

Raymond mill is widely used to grind materials in the fields of building materials, mining, metallurgy and chemical industry. The materials must be non-flammable and non-explosive materials such as: limestone, calcite, barite, dolomite, potassium feldspar, marble, talcum, gypsum, rock phosphate, iron ore, active carbon, carbon black, fireproof materials, heat preservation materials, chemical materials and so on (around 300 kinds of materials). The hardness of the material should be less than 7 in Moh's hardness and its humidity should be less than 6 percent. The granularity of the end products can be adjusted from 30 to 325 meshes.

Advantages

1.The spare parts adopt the highly wear-resistant material, which guarantee they have long service life;
2.The electric system adopts centralized control. It is separated with the work shop where the grinding mill is located, which can guarantee the worker’s health while the machine is running;
3.Few dust pollution and few noise is generated when the mill is running.

After the materials enter the grinding room of the main equipment, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of the main shaft. The blade carries materials to the space between the grinding roll and grinding ring, and materials are ground as the grinding roller rolls. After being ground, the powder is selected by classifier via the cycle wind of the blower and the oversize powder will go back to the grinding cavity for regrinding. The qualified powder is brought into the powder collector together with airflow. The powder comes out as end products while the airflow goes back to the powder collector in cycling to make the machine work normally. The remaining airflow comes out after purification by dust collector.
